Swap one citrus for another and keep the same tartness, or build a shelf-stable acid-adjusted citrus solution from water, citric acid, and malic acid.

This matches tartness (total acidity), not flavor — lemon won't taste like lime. It's a starting point for a fair swap, not a flavor match. Always taste and adjust.
Recipe ratios are the commonly published starting points used in modern bar prep — real fruit varies by ripeness and season, so taste against a fresh reference and adjust before batching it into service. A kitchen gram scale is strongly recommended for the acids; scoops and spoons aren't precise enough.
Dissolve the acids into the water (warm water speeds this up), then chill. Citric acid brings bright, sharp acidity; malic acid adds a rounder, greener tartness — together they get closer to real citrus than either alone. Keeps refrigerated about as long as fresh juice.
Fresh citrus is still the gold standard for flavor — an acid-adjusted solution is a tool, not a replacement. It shines when you need consistency across a huge batch, when citrus is out of season or wildly variable in tartness, or when you want a longer shelf life than fresh juice allows for high-volume event or catering service. Most bars that use it still cut it with a little real citrus zest or juice for aromatics.
